The 
    clean does not seem to clean all of the classes directories any more.  Shouldn't it delete all the class 
    directories and build artifacts?

    Anyone 
    else having issues building lately?  
    My build was failing with an invalid class file format in one of the 
    JPA tests, so I did an "ant clean" and "ant" at the root and 
    got:
     
     
    C:\Engineering\EclipseLink\dev>ant
    Buildfile: 
    build.xml
     
    build-core:
         [echo] 
    jpaproto.build.location = 
    'C:\Engineering\EclipseLink\dev\jpa\plugins\javax.persistence'
     
    clean:
       [delete] Deleting directory 
    C:\Engineering\EclipseLink\dev\jpa\plugins\javax.persistence\classes
       [delete] Deleting: 
    C:\Engineering\EclipseLink\dev\jpa\plugins\javax.persistence_1.99.0.jar
     
    compile:
        [mkdir] Created dir:

    BUILD 
    FAILED
    C:\Engineering\EclipseLink\dev\build.xml:156: 
    The following error occurred while executing this 
    line:

    Any 
    ideas?
